VALVE FOR HEATING-SYSTEMS.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed May 26, 1906. Serial No. 318,8595

To all whom it may concern.-

Be it known that I, ALBERT P. BRooMELL, a citizen of the United States,residing at York, in the county of York, State of Pennsylvania, haveinvented certain new and useful Improvements in Valves for HeatingSystems, of which the following is a description, reference being had.to the accompanying drawings and to the letters and figures of referencemarked thereon.

The invention relates to improvements in the valve shown in UnitedStates Patent No. 657,059, August 28, 1900.

The objects of the invention are to seat the valve, hold itsoperating-handle in its locked position, and keep the valve-stemproperly packed, all by one and the same spring.

These objects I accomplish by the construction shown in the accompanyingdrawings, in which Figure 1 is a central vertical section of my improvedvalve. Fig. 2 is a horizontal sec: tion on line 2 2, Fig. 1. and Fig. 4'is a perspective view, of the valvestem and the disk valve separated.

A designates the valve-casing, having a closed upper end A and thereprovided with a circular series of recesses a. One side of the casing isprovided with a threaded nipple A to connect with the radiator, and thebottom of the casing is closed by a removable externally and internallythreaded cap A for connection with the source of supply.

The casing is divided just below the outletnipple A by a transversepartition 0/, having a semicircular slot a, and the center of'thepartition is connected with the center of the upper end A by an integraltube a The opening through the partition at the lower end of the tube isreduced so as to forman annular shoulder a to receive the packingmaterial a above which is a washer a. 4

B is the valve in the form of a disk, having an annular recess b in itsupper face, within which fits a non-metallic packing-ring b, ofasbestos, fiber, or other suitable material. The upper or working faceof this packingring projects above the valve-disk B, so that it engagesthe under side of the partition a and prevents any metallic part of thevalve from coming into contact therewith. The periphery of thevalve-disk B is spaced from the interior of the casing A. The valve B bFig. 3 is a plan view,

is provided with a series of circularly-arranged apertures 11 toregister successively with the slot or opening a in partition (1/.

The central collar b of the metal disk B is lower than the peripheral orouter flange, and upon it rests the lower shouldered end of thevalve-stem which stem passes down through the tube a" and through Washera, packing a", and annular shoulder a.

The bore of the collar 7) is generally square, but has one cornerflattened, as at b, and the squared portion 0 of the valve-stem issimilarly flattened, as. at 0, so that the valve-disk must be properlypositioned before it can be placed on the stem. When in place, the valveis secured by means of the cap-nut b screwed on the lower threaded endof the stem.

7 O is a sliding flanged 'collar on the valvestem'in the upper end ofthe tube a and between this collar O and the washer a at the bottom ofthe tube is placed a spiral expansion-spring O through which thevalve-stem works.

D- is the horizontally-disposed handle, pivoted to rock vertically onthe upper end of the valve-stem by means of a slot d, through whichpasses the flattened upper extremity 0 secured therein by a transversepivot-pin D and causes it to pull upwardly on the stem O, and so holdthe non-metallic face I) of the valve B a ainst its seat. -Furthermore,the spring performs the very important function of compressing thepacking material a? through the medium of the washer a, and so thevalve-stem is kept constantly packed.

The handle is provided .at the lower side of its outer end beyond itspivot with a proj ection (1 which engages the collar O, and at theopposite side of its pivotal point the handle is provided with adepending lockinglug d to engage any one of the recesses a in the up erface of the valve=casing, the upward orce of the spring on projection dtending to press the lug 05 down and hold the handle against accidentaldisplacement. Thus the spring performs the three important functions ofseating the valve, keeping the valve-stem packed, and holding the handlelocked.

.When it is desired to move one of the valve-apertures If into registerwith the slot (L2, the handle l) is raised, causing the projection dto-bear down on and depress the collar C, when by turning the elevatedhandle in the proper direction the valvetwill be rotated to throw theapertures I)- successively into and out of register with the slot (1thus admitting or shutting oil the lluid to the extent desired.

In order to make these valves suital')l l'or different sizes oiradiators, it is only necessary to change the size of the apertures b inthe valve- .lisks and not change the size of the valves themselves. Forinstance, a So. 1 valve for a radiator of twenty-liw feetheating-surface will have holes one-eighth of an inch, while a No. 2valve for a radiator of liftv or sixty feet heating-surface will haveholes of three-sixteenths of an inch, and so on.' Thus withinterchangeable valve-disks valves" of only one size are required forall sizes of radiators.

The valve 1s particularly adapted for use -with the steam-heating systemshown in Patent 650,778, May 29, 1900; but it may be used in otherrelations.

I do not restrict myself to the particular construction shown, since thesame may be considerably changed without departing from the scope of mylnvention.

H avingthus described my mvcntion, what I claim as new, and desire tosecure by Letters Patent,'is

A valve comprising a casing provided with locking-recesses, arotaryvalve controlling the passage of fluid through the casing, a stem forthe valve, a handle 011 the stem having a portion to engage any one ofsaid recesses, and a spiral spring between the handle and a part oi thecasing to hold the valve to its seat and also hold the handlein itslocked ositions.
